I do not know what you mean by DBNULL. SQLite has a NULL type of variable. But it has no characters in it, it is always null. You can use the function typeof(value) to find out the type of a value: <http://www.sqlite.org/lang_corefunc.html> "The typeof(X) function returns a string that indicates the datatype of the expression X: "null", "integer", "real", "text", or "blob"."
